Free textbooks, virtual labs, interactives, and activities for building an ecology unit: 

Textbooks: If you want to use a textbook to structure your unit, check out Environmental Science: Earth as a Living Planeta 658-page download.

There's also CK-12's Intro to Ecology, with 35 sections covering ecosystems and related topics. Sections include reading, related videos and links, and online practice questions. You can easily create your own "Flexbook" with only the sections you want to cover. The Ecology chapter is part of CK-12's Life Science textbook. 

HippoCampus Environmental Science VideosInformation on Earth's atmosphere, water, geology, and ecosystems.

Exploring Planet Earth: Free online course presented in 10 modules covering Earth's systems and resources.

Here are some links to free resources for explaining and learning about various ecology topics through interactives, labs, assignments and activities. 

Levels of Organization: This Glencoe Virtual Lab is an investigation of how competition for natural resources affects population growth. Grow two species of Paramecium, compare growth curves, answer journal questions.

Food Chains/Webs

  • Energy Flow in Ecosystems: Shows how energy flows through a food chain between producers, consumers and decomposers. Includes a short quiz.

Predators and Prey

  • Predator-Prey Simulation: Examine predator and prey interactions, in this case, wolves and deer. Set three parameters for the predator: aggression, birth rate, and dependency upon prey as a food source. Then run a simulation to see how the populations change over time.

Symbiosis and Other Interactions:

This video on symbiosis is part of a TED-Ed lesson that includes questions and additional information. 

Nature Cycles:

  • Water Cycle: Interactive diagram with a multiple choice quiz.
  • Carbon Cycle: Travel the cycle with this interactive game. Click the "For Teachers" link for a related lesson plan and additional resources.
  • Carbon Cycle Investigation: A longer simulation activity in which sources of carbon, and human effects on the cycle are identified.
  • Nitrogen Cycle: Visualize the flow of nitrogen in the environment.

Photosynthesis and Respiration

  • Virtual Lab: A simulation investigating the effects of environmental conditions on photosynthesis.
  • Interactive Google Doc: 

Earth's Biomes:

  • Six Virtual Biomes: Description of plant and animal life in the major biomes and ecosystems.

Habitats and Ecosystems: 

  • DK Find Out: Interactive illustrations on plants and animals in different habitats. 

Biodiversity: 

  • Backyard Biodiversity: Kids search for animal life in microhabitats close to home. Involves observation, classification, and species mapping. Includes links to several citizen science projects.
  • Endangered Species Assignment: Using earthsendangered.com, create a graphic organizer comparing 4 endangered species from an area of the world.

Free resources to supplement your study of plants, flowers, and trees, including interactives, free readers, and virtual forests and trips. 

Start with The Science of Soil which offers free lesson plans and interactives on the properties of soil. There are also hands-on activities, like measuring basic soil chemistry in your backyard, and videos on how different produce is grown.

To study plant processes, check out this interactive doc on photosynthesis and cellular respiration: 

The Great Plant EscapePresents information in six "case files" so that kids can solve the mysteries of plant life. Covers: parts of plants, life cycle of plants, soil, seeds, and plant reproduction. Each case file has several hands-on activities or experiments that can be done.

                                

 Photosynthesis: An interactive that     explains the process.

 Photonsynthesis Videos: From NeoK12; also has links to quiz games and puzzles   

Life of a Tree: Interactive 

Flower Parts: An interactive describing the parts of a flower and how flowers reproduce. Here's another one that mentions pollination.                       

                   

 

 

 

 

 

 

 

 

Plant Reproduction: from Glencoe Life Science; 32 pages

MicroorganismsText and interactives that teach about fungi and algae

Free BrainPop MoviesThese cover: how flowering plants produce seeds; photosynthesis and respiration; gymnosperms and angiosperms

 

 

Dr. Arbor Talks Trees: Animated lessons about tree anatomy and identification. Includes teachers guide.

Take a walk in the forest and ID trees using this dichotomous key.

 

10 Free Resources for Learning Chemistry

Explore chemistry concepts using a variety of free resources, including video lessons and demos, labs and activities, worksheets and games: 

1. American Chemical Society has lesson units and activities for elementary, middle school, and high school chemistry that can be downloaded for free:

  • Inquiry in Action: Elementary through middle school students learn key concepts through a series of activities. 
  • Middle School Chemistry:  Six chapters of lesson plans can be downloaded covering matter, changes of state, density, the periodic table and bonding, the water molecule, and chemical change. Each chapter includes animations and activities.

2. GPB EducationGeorgia Public Broadcasting provides free fundamentals of chemistry and physics courses for high school students. The content is delivered through 30-minute video lessons, and accompanying note-taking guides and worksheets.

3. Creative Chemistry: This site provides PDF worksheets and guides, and PowerPoints on a number of chemistry topics. There’s a molecules section that allows you to view and manipulate molecular models, and a section with chemistry games and puzzles.

4. Chemistry Now: A weekly, online video series that explores the science of the everyday. The short (5-minute) programs explain the chemistry behind ordinary objects and occurrences, such as cheeseburgers and chocolate, changing leaves and the fear response. The series also takes a look at chance discoveries in chemistry (like Kevlar) , and the work of today’s top scientists.

 

5. Heating PlasticsLearn more about plastics with this interactive game. 

6.   Periodic Table of Videos: As its name implies, this site is a modern version of the Periodic Table of Elements, with short videos explaining each element’s significance and how they’re used. 

7. goREACT: From the Chicago Museum of Science and Industry, this site lets you create virtual chemical reactions by dragging elements from the periodic table to a “reaction area." 

8. Chemical Symbols Game: This game is designed to help players identify the first 92 elements by their symbols. Players must combine the correct elements in the "reactor" to make various compounds. Scroll to the bottom of the page for more links on chemical equations and the periodic table.

9. AP Chemistry Videos: This comprehensive collection is found at Curriki.

10. Chemistry GamesInstructions and patterns for making and playing several card and board games to teach chemistry topics.
